Breast implants and heavy pregnant!

So this is probably an odd one to put on here but I had my breasts done when I was 21 because I had nothing and I mean nothing not even an A cup I couldn't fill a bra as was slightly tubular shape no side or under boob and it really effected me as I'm quite a big girl very tall and always fluctuated in weight! Anyway I had my first baby December 2017 and I didn't really feel like it changed them atall but I then fell pregnant again four months after and I'm due baby number 2 at the end of this month! I'm starting to feel quite body conscious now as I've put on soooo much weight this time round wanted to eat everything and I can't help but feel like my boobs feel heavier this time and sagging are there any breast enlargement ladies out there who have had babies after having them done and feel the same as me and would you say they still look like fake boobs? Sorry for random post just getting to end of pregnancy and feeling massive and crappy I guess ahahaha can't wait to loose weight and feel better in myself and have energy to run after my 1 year old! X
